From b77d6adc922b8bbf8b16b67f567958c42962cf88 Mon Sep 17 00:00:00 2001 From: Paolo 'Blaisorblade' Giarrusso Date: Tue, 21 Jun 2005 17:16:24 -0700 Subject: [PATCH] uml: make hw_controller_type->release exist only for archs needing it With Chris Wedgwood As suggested by Chris, we can make the "just added" method ->release conditional to UML only (better: to archs requesting it, i.e. only UML currently), so that other archs don't get this unneeded crud, and if UML won't need it any more we can kill this.
